Title: Interlaced matching and interpolated matching method for fingerprint
Inventor: IRIE HIROMI
IPC: G06T7/00
Filed: 1987-03-12
Abstract: PURPOSE:To shorten a matching process time without overlooking a matching coincidence point by employing both interlaced matching and interpolated matching. CONSTITUTION:In general, a finger print has 12 upheaving lines/5mm on average. The image signals for matching ore therefore converted into binarization signals for the size (96X96 bits) of about 5mm<2>. The upheaving lines are present at intervals of eight bits and there are 3-4 bits of 0 or 1 continuously in a binarization series on average. For the purpose, if retrieval is carried out at intervals of 3-4 bits (1/2 of upheaving line pitch), then at least one upheaving line or groove part is matched. Therefore, the interlaced matching is performed at 3-bit intervals to reduce logical time shortening effect to 1/3. Further, when the matching rate of the interlaced matching exceeds a constant reference, the interpolated matching is carried out to improve the matching rate.
